Purpose: To evaluate a method to identify condylar sag intraoperatively by clinical examination after bilateral sagittal split osteotomy (BSSO). Methods: We. Condylar sag is an immediate or late alteration in the position of the condylar process in the glenoid fossa after the fixation of the osteotomy. Peripheral condylar sag (type II) had developed in three of these patients. In 15 patients central sag was diagnosed. One-week postoperatively, three patients.

As with any surgical procedure, various preoperative, intraoperative, and postoperative complications may occur. The most important part of surgery for avoiding such complications is the positioning of bony fragments and rigid fixation.

The incidence of postoperative wound healing problems following sagittal ramus osteotomies stabilized with miniplates and monocortical screws. The Cochrane Collaboration Tool for the assessment of risk of bias was used to conduct this assessment. Subjective symptoms of sensory alteration are more important after axonal rather than with demyelinating injuries [ 29 ]. Nasotracheal intubation may also cause swelling of the soft tissues in the nasotracheal area, blocking the Eustachian tube, and precipitating middle ear effusion [ 38 ].


Studies not meeting the inclusion criteria were excluded from further evaluation. Clinical relevance Oral and maxillofacial surgeons, orthodontists, and the surgical team need to prevent such complications during preoperative, intraoperative, and postoperative periods to increase the safety of orthognathic surgery procedures.
